PS Science was launched in 2006 as a project of the Crossroads Community Outreach Foundation, an initiative of Crossroads School in Santa Monica, in response to a chronic deficit in public school education —the lack of meaningful early elementary school science education.

Inspired by the magic and wonder that master science teacher Dr. Selma Sleven brought to the lives of countless Crossroads elementary students, PS Science was created to bring that same powerful and inspiring experience to children in underserved communities across Los Angeles.

Crossroads School provided critical financial support and resources until 2018, when PS Science grew large enough to become its own separate nonprofit organization.

At the time PS Science was conceived, the most recent analysis of science exam scores ranked California’s students at the bottom, along with Arizona, Mississippi and Hawaii. In June 2019, PS Science 4th grade students performed 99% better than the national average in a standardized science assessment!
